12．You won't lose weight        you go on diet and take exercise regularly．（　�。�
A．ifB．unlessC．becauseD．so

分析 除非你經(jīng)常節(jié)食和鍛煉，否則你是不會(huì)減肥的．

解答 答案B．
so表示因果意義的并列連詞，并列連詞用來連接平行的詞、詞組和分句．因此可排除D．if"如果"，引導(dǎo)條件狀語從句．unless"除非，如果不"，在意義上相當(dāng)于if…not，因此在有些場(chǎng)合中unless與if…not可互換使用，引導(dǎo)條件狀語從句．because"因?yàn)?，引導(dǎo)原因狀語從句．分析可知前后兩句話之間是邏輯上的"條件"關(guān)系，可排除C；再結(jié)合句子所表達(dá)的意思可知答案選B．

點(diǎn)評(píng) 本題考查從屬連詞的用法．連詞的用法辨析，要注意分析主從句之間的邏輯關(guān)系，再確定相應(yīng)的連詞，同時(shí)注意不同的連詞的語義及用法區(qū)別．

2．Imagine shopping in another country and spotting a beautiful scarf．The salesperson tells you the price，（32）but it's more than you want to buy．What do you do？
The answer depends largely on what part of the world you are in．Are you visiting Southeast Asia，the Middle East，Latin America or Africa？In these places，prices often are not set in stone．In fact，customers （33）are expected（expect） to bargain before agreeing to a price．
On the other hand，in North America，Europe and Australia，bargaining is rare and often not allowed．The price （34）listed（list） on a price tag cannot be changed．
Large stores and malls usually don't allow bargaining．On the other hand，outdoor stalls and flea markets，even in Western countries，usually allow bargaining．When in doubt，consult a guidebook---or （35）better（good） yet，a local friend．
（36）Although/Though/Whilebargaining custom vary，a few rules of etiquette apply in most cultures．First，avoid wasting people's time．If you don't intend to make a purchase，don't start bargaining．While bargaining，it is OK to walk away．But once you agree to a price，you （37）must buy the item．
Even in countries （38）that/which don't allow bargaining，you may find plentiful opportunities to save money．Many stores sell old items on clearance．Others offer discount cards to regular customers．Some of these can function as credit cards （39）within/in the store，and a few can even be used elsewhere．
（40）Wherever you go，understanding local customs can help you find good prices．

3．Every year in late April，students at Renmin University of China become the subjects of admiration and jealousy of their peers on other campuses in Beijing．Why？（36）F It has been a unique tradition of Renmin University for a decade．
Having fun is just one dimension of the spring break．Field trips，voluntary work，and social projects are all on students'to-do lists．Experts say the spring break is not just for students to enjoy a few days off，but for them to gain new experiences beyond the campus walls．
Push them out
The traditional Chinese belief of the exploration of knowledge and truth emphasizes"reading 10，000 books and travelling 10，000 miles"．（37）E But while Chinese universities have the tradition of spring outings，what's the benefit of making spring break an institution？
Qin Jianguo，from Shenzhen University，thinks the idea of the spring break in some universities in China comes from the intention of pushing students out of the ivory tower to experience more diversity in their lives．He said，"Take traveling for example．A week traveling is a very different experience to a one-or two-day outing．When put out in an unfamiliar context，students are expected to acquire the spirit of teamwork and compromise．（38）D"
Diverse approaches
Many countries have similar vacations in the middle of the semester for students to do things out of their own interest．Taking Japan as an example，instead of partying like their US counterparts，many Japanese students choose to work as interns or engage in study-related projects．
（39）C Pan Yingzhao，22，majoring in finance at Renmin University of China，participated in a social project on the theme of"The Chinese Dream"．She and her teammates interviewed people on the street to see how they understood"The Chinese Dream"．"Through this activity，I learned how to communicate with strangers appropriately，"Pan said．
（40）B
Apart from Renmin University，only a few other universities，have a spring break for their students．The concept in China is still far from the culture and norms built around it in the US．
Wei Xiang，a professor specializing in holiday economics at Beijing International Studies University，said that the spring break is a good experiment for universities to make study schedules smoother in order to give students more options to arrange their own leisure and study activities．

A．Not a legend
B．Not a trend yet
C．As for Chinese students，many tend to do volunteer work
D．They have to learn survival and communication skills as well
E．It does indicate the importance of experience as much as theory
F．Because they get a week off in the middle of term，the so-called spring break
G．To sum up，a spring break helps students expand their horizons and improve ability．

20．Doctors'moonlighting is becoming popular in hospitals around China．It has not only raised a lot of heated discussions in the media，but also caught the attention of the central government in Beijing．
On December 26，a spokesman of the Ministry of Health stressed that the ministry was firmly against doctors'moonlighting，while strict regulations should be applied to doctors taking part-time jobs，the Xinhua News Agency reported．
Last year，the Ministry sent out a notice to a variety of health organizations to speed up the reform of their personnel （人事） system．According to the notice，medical organizations can hire medical experts as part-time doctors but such activities should take place under the hospital's management and regulations（規(guī)定）．
As for moonlighting--meaning that the doctor provides medical service without the permission of the original hospital--such activity goes against China's Practicing Doctor Law，Xinhua reported．
In China，doctors used to be controlled by hospitals and they could work for only one hospital．However，as China's medical personnel system reform developed，it has been recognized that medical human resources，just like human resources in other areas，should be shared by the whole society．But on the other hand，doctors'taking part-time jobs should follow the relative regulations applied in the medical field．
First of all，they should follow relative government laws and regulations．They should also follow the rules and regulations set by the medical organizations they work for．In addition，they should pay taxes for their income from the part-time jobs．What matters most is that they should first finish their regular jobs as required and be responsible for patients to ensure qualified and safe medical treatment．
67．What is the greatest difference between moonlighting and taking part-time jobs？C
A．Doctors can earn more money by moonlighting than by taking part-time jobs．
B．Doctors pay fewer taxes for the money made by moonlighting than by taking
part-time jobs．
C．Taking part-time jobs is permitted by hospitals while moonlighting is-against
the present regulations．
D．Doctor's part-time jobs，instead of moonlighting，are encouraged by health organizations．
68．From this passage we know that doctors are allowed to  nowadays．B
A．only work for one hospital        
B．work for more than one hospital
C．work any time when they are free   
D．be out of control of hospitals
69．The passage is taken most probably fromD．
A．a(chǎn) notice sent out by the Ministry of Health 
B．regulations made by health organizations
C．China's Practicing Doctor Law
D．a(chǎn) magazine or a newspaper
70．According to the passage，we have got to know thatC．
A．a(chǎn)ll doctors around China prefer moonlighting to part-time jobs
B．moonlighting has been permitted by China's practicing Doctor Law
C．taxes should be paid for the money doctors get from their part-time jobs
